Andalusite Details
Product Description
Andalusite is a superior high-alumina refractory material.
lt has the characteristics of high-temperature resistance, chemical corrosion resistance, heat resistance, high-impact resistance and high thermal mechanical strength. lt has a wide range of application and high economic value.
It is mainly used in steel, ceramics,cement, glass and other industries. The consumption of iron
and steel industry accounts for more than 65% of Chinese market consumption.
Andalusite is an aluminosilicate mineral, which is the raw material for making refractory materials and porcelain in spark plugs. It is a crystalline material that does not need to be calcined before use. As a shaped or unshaped refractory, it has good performance under harsh conditions, so it is used in industries that require high temperatures, mechanical strength, and chemical impact. It is also an energy-saving refractory raw material, it is directly used for making bricks. The characteristics of it are obvious; the temperature of mullite is low; the thermal expansion during the conversion is low; the crystal is coarse and can be used as aggregate. All of this allows it to be used directly to make fired or unfired refractory bricks without calcination and saves a lot of energy.
The use of andalusite in industry is mainly based on its high temperature resistance. It has higher fire resistance performance, refractoriness can reach 1800 ℃ or more, and it is resistant to quenching and sudden heat, high mechanical strength, strong thermal shock resistance, strong slag resistance, high load conversion point, and is resistant to quenching and sudden heat, mechanical High strength, strong thermal shock resistance, strong slag resistance, high load conversion point, and high chemical stability and strong chemical resistance.
The main application is as follows
High grade product : ceramic kiln furniture;
Medium grade product : fixed refractory brick products;
Low grade product: Refractory castable products.
